Slow Boot Since Installing OS X 10.10.3
Hello All
Since installing Yosemite 10.10.3 on my MacBook Pro this morning I noticed that the boot up seems slower than usual. When I press the power button the chime sounds almost straight away then the screen stays black for about 10/15 seconds before the Apple logo appears. At this point the computer boots straight to the login screen. Everything else works fine. Previously there didn't seem to be a black screen between the chime and Apple logo. Any suggestions as to what this could be?
Thanks!
MacBook Pro with Retina display, OS X Yosemite (10.10.3)
